Data Sources & Methodology

Every number on Wage Place traces back to an official or published source. Below is a full account of what data we use, where it comes from, how we calculate results, and where the limitations are.

Minimum Wage Lookup

HighUpdated: January 1, 2026

Sources

U.S. Dept. of Labor — Wage & Hour Division

Primary source for all federal and state rates

DOL Minimum Wage Overview

Federal minimum wage and exemptions

State labor department publications

Individual state agency pages for local ordinance rates

Methodology

State rates are sourced directly from DOL Wage & Hour Division publications updated January 1, 2026. Local ordinance rates (city/county) are sourced from individual state labor department announcements. ZIP codes are mapped to the nearest applicable jurisdiction. When multiple rates apply, the tool displays all tiers and highlights the legally applicable rate (highest of federal, state, and local).

Limitations

Local ordinance coverage is not exhaustive — some smaller municipalities with local minimum wages may not be represented. ZIP-to-jurisdiction mapping is based on ZIP prefix ranges and may not be precise for ZIP codes that span multiple jurisdictions. Always verify with your state labor department for compliance decisions.

Compensation Band Calculator

HighUpdated: Calculated in real time

Sources

WorldatWork — Compensation glossary

Standard definitions for compa-ratio, range penetration, and spread

SHRM Compensation Practices

Industry standard methodology

Methodology

All calculations use standard compensation formulas: Compa-ratio = salary ÷ midpoint. Range penetration = (salary − minimum) ÷ (maximum − minimum). Range spread = (maximum ÷ minimum) − 1. No external data is used — all results are derived from the values you enter.

Limitations

This tool calculates band position — it does not validate whether your band is market-competitive. Use the Salary Range Builder for market benchmarking.

Salary Range Builder

BLS Occupational Employment and Wage Statistics

Primary source for occupational wage data by metro area

BLS Metropolitan Area Occupational Employment

Regional wage differentials for location adjustment

Radford Global Compensation Database (aggregated)

Technology and general industry benchmarks

LinkedIn Salary Insights (aggregated)

Cross-validation for technology and professional roles

Methodology

Base ranges represent the 25th–75th percentile of U.S. compensation for each job family and experience level, aggregated from BLS OES data and third-party compensation surveys. Location adjustment applies a cost-of-labor multiplier derived from BLS metropolitan area wage differentials. Range spreads follow WorldatWork design principles: 40–50% for entry-level, 50–60% for senior roles.

Limitations

Ranges are market estimates, not guarantees. Industry, company size, funding stage, and specific role responsibilities significantly affect appropriate pay levels. These ranges are most accurate for general industry in major U.S. metros. Specialized industries (finance, biotech, entertainment) may vary substantially.

Cost of Living Calculator

Medium — composite estimatesUpdated: 2024–2025

Sources

Numbeo Cost of Living Database

City-level cost indices for housing, food, transport, and misc

C2ER Cost of Living Index (COLI)

Quarterly cost of living index by metro area

BLS Consumer Expenditure Survey

Category weights (housing 33%, transport 18%, food 16%, etc.)

Methodology

COL indices are composite scores derived from Numbeo city data, C2ER COLI quarterly reports, and BLS regional CPI data. Index of 100 = U.S. national average. Salary adjustment formula: equivalent salary = current salary × (destination index ÷ origin index). Category weights follow BLS Consumer Expenditure Survey allocations.

Limitations

Indices represent metro-area averages. Costs within a metro vary significantly by neighborhood. ZIP codes map to the nearest metropolitan area — suburban and rural areas within a metro may have lower costs than the index suggests. Data is updated annually.

Pay Equity Analyzer

High — based on your dataUpdated: Calculated from uploaded data

Sources

EEOC Pay Data Reporting Guidance

Methodology reference for pay gap analysis

BLS Methods for Measuring Pay Gaps

Statistical methodology reference

Methodology

All calculations are performed on data you upload — no data is stored or transmitted. Average salary per group is calculated using arithmetic mean. Gaps are shown as percentage difference from the overall workforce average. Groups with fewer than 2 employees are excluded to protect individual privacy.

Limitations

Raw pay gaps do not account for differences in role, level, tenure, location, or performance — these are unadjusted gaps. A gap does not necessarily indicate discrimination. Controlled pay gap analysis (adjusting for legitimate factors) requires more sophisticated statistical modeling. Consult legal counsel before taking action on pay equity findings.
